Shift + mouseover with jQuery

It is not necessary to store in a variable when the shift key is pressed and released. You can achieve what you are trying to to like this:

$('#selector').mouseover(
    function(e){
        if (e.shiftKey)
        {
            console.log("the shift key is pressed");
        }
    }
);

check this on the keypress event:

$(document).keypress(function (e) {

  if(e.shiftKey) {
    pressed = true; // pressed is a global varialbe. Be carefull of the scope
  }

}

then on the keyup:

$(document).keyup(function(event){
   pressed = false;
});

then do:

$("#selector").mouseover(function(e){
    if(pressed) {
        console.log("the shift key is pressed");
    }
});

---

or the other way around :

$("#selector").mouseover(function(e){
    isover = true;
});

and

   $(document).keypress(function (e) {

      if(e.shiftKey) {
        alert("do something")
      }

   }
